The present invention relates to paper dishes, that is, to dishes madeof any suitable fibrous stock, whether paper or resembling paper, andparticularly to such a dish having a re-enforced rim. The dish may becircular, polygonal, or any suitable form, molded or formed in anysuitable way. rllhe paper stock-may be single or multiple ply with orwithout incorporatin a binder, andv 10 the dish may be coated withparailin or otherwise treated to resist moisture and to withstarfdwashing.

The dish, which may consist of one Vpiece of stock, has a rimre-enforced to give strength and rigidity thereto.

which is preferably triple-enforced, 1s

' formed from a continuation yof the stock of the dish folded inoverlying portions and .where triple-enforced, into three overlyingportions. The inner surface of the -rim is referably made to lieinuninterrupted conormity with the interiorsurface of the dish.Irrespective, however, of the continuity of the inner rim and dishsurfaces, but prefer'- 26 ably embodying this construction, the dish mayhave an upturned side wall, the upper portion of which is recessed, andthe folds of stock may be anchored in said recess. Furthermore, the rimmay be highly compressed and practically solidified, in which case thefolds thereof are rigidly set to pery manent gage dimensions. So formedand treated, the rim provides a substantial ref enforcement for the dishagainst deforma# tion in handling or in use. Where the rim istriple-enforced, the folds of stock may consist of a base portion, areversely extending intermediate portion, and an enclosed terminalportion, the inner surface of the intermediate portion lying inuninterrupted conformit with the interior surface of the dish. In t especific embodiment described hereinafter, the base and intermediateportions are joined by means ofa secedge of the terminal portion to forma flat edge for the dish, thus facilitating the handling thereof.

Irrespective of the manner in which the rim of the dish is re-enforced,the invention comprehends as another of its parts, a paper dish havingan upturned side wall and a re-enforced rim formed from a continuationof the stock of the side wall folded into overlying portions, the bottomof the dish having an annular' depression which serves as The rim,

tion of stock lying flat over the peripheral a stand for the dish tokeep the bottom thereof out of contact with wet or damp surfaces uponwhich the dish might be placed. Preferably the bottom of the dish isslightly concaved outwardly to provide against Warpmg and t'o increasethe depth of the dlsh, and the annular depression is situated adjacentthe upturned side wall to provide a stand of sufficient diameter tofirmly supp ort the dish when in use. Preferably one side of the annulardepression lies in uninterrupted conformity with the `upturned side wallso that the latter has aV rounded section of stock -joining it with thebase tov sup- *port 1t 1n the upturned or inclined position.

The connecting section Vthus formed provldes a-stronger support for theside wall 4in a position inclined to the bottoml than would be providedwere the connection a corner or sharp edge.

Whether or not the dish is provided with an annular depression to serveas a stand therefor, but preferably so, the invention comprehends asstill another of its parts', a

one piece paper dish having a rim formed from a continuation. of thestock thereof which is convoluted, preferably outwardly j l of saiddish, to form a re-enforced rim or bead. (Where the bead is highlycompressed and practically solidified under great pressure theconvolutions of stock are rigidly set topermanent gage dimensions andthe rim re-enforces the dish against deformation under pressure inhandling. The bottom of the dish may have an annular' depression toserve as a stand therefor, one side of which preferably' lies inuninterrupted conformity with the upturned side wall to providev arounded connecting section betweenait and thebottom of the dish.

In the accompanying drawings illustrating the preferred embodiment ofthe invention in application, as an example, to a dish of single-plystock,

Fig. 1 is a view in elevation of the dish partl in section and partly infull view; and ig. 2 is a plan view of the dish shown in Fig. 1.

In the embodiment illustrated in Fig. 1, the dish has aI bottom 1slightly concaved outwardly, an upturned side wall 2, and a re-enforcedrim 3. The rim 3 is formed from a continuation of the stock composingthe dish and comprises a base portion 4, an intermediate portion 5, asection 6 joining the base and intermediate portions, and'a` terminalportion 7 enclosed between the base and intermediate portions. Thejoining section 6 lies flat over the raw edge of the terminal portion 7,so that said edge is concealed, and is also protected lfrom moisture,which might` otherwise have access thereto either from without the dish,when it is placed in water to be washed, or through capillary attractionfrom its contents. The inner surface of the rim lies in uninterruptedconformity with the inside surface of the dish. Thus while the innersurface of the rim is made to constitute part of the interior sur-k'communicated to the bottom will not be concentrated at any one pointbetween the side and bottom, but will be distributed throughout theentire curved portion, so that, while this portion may yield, understrain, it will be perfectly resilient and will always return to theform in which it was molded. As a result, the sides of the dish will notbecome distorted under ordinary conditions of use.

In the manufacture of the dish the resiliency and permanency of thecurved connection portion or annular depression 9 is greatly increasedduring the molding operation, by so forming the molds or dies that thepressure to which this portion 9 is subjected, will be greatly in excessof that applied to the side and bottom, thereby causing this portion tobe highly solidified.

The formation of the bottom 1 slightly concave is important in that thisconstruction also assists in preventing deformation n use much moreeffectively than if it were The folds of subjected, in forming,to apressure preferably of about 4000 to 6000 pounds per square inch, underwhich pressure the parts become highly compressed and practicallysolidifiedv and are rigidly set to permanent gage dimensions.

Having thus described my invention, what I claim is: j
